ABSTRACT

The present invention relates to a composition for manufacturing optical elements with negative optical dispersion, and an optically anisotropic body prepared therefrom. According to the present invention, the optically anisotropic body showing stable reverse wavelength dispersion can be prepared more simply by using the composition for optical elements, and it is possible to apply the same to liquid crystal display devices as an optical film such as a thin-layer broadband λ/4 plate.

TECHNICAL FIELD

The present invention relates to a composition for manufacturing optical elements with negative optical dispersion, and an optically anisotropic body manufactured therefrom.

BACKGROUND OF ART

A phase retarder is an optical film for realizing a wide view angle of a liquid crystal display, for example. The phase retardation value of the phase retarder depends on a wavelength, and wavelength dispersion of the phase retardation value is largely classified into the following three categories. Namely, the wavelength dispersion of a phase retardation value may be classified into normal dispersion in which the phase retardation value has a larger wavelength dispersion at a shorter wavelength side, flat dispersion in which the phase retardation hardly changes from the short wavelength side to the long wavelength side, and reverse dispersion in which the phase retardation value has smaller wavelength dispersion at a shorter wavelength side. In the case of the phase retarder, it is preferable to show the reverse dispersion because it has a certain phase difference (λ/2, λ/4, and so on) in a wide wavelength band.

However, since most of the phase retarders made of common resin films show the normal dispersion, various kinds of liquid crystal compositions which can provide the reverse wavelength dispersion have been suggested. Commonly, liquid crystal compositions include a rod-type liquid crystal material and a non-liquid crystal material that is aligned perpendicularly to the liquid crystal material. However, the reverse wavelength dispersion is not induced when the mixing ratio of the non-liquid crystal material is low, and the liquid crystal composition loses the liquid crystalline characteristics when the mixing ratio is high. Furthermore, when the content of the non-liquid crystal material is raised for increasing the reverse wavelength dispersion, the birefringence relatively decreases because the reverse wavelength dispersion and the birefringence have complementary characteristics.

Therefore, the developments of materials which can induce strong reverse wavelength dispersion and compositions for optical elements which can induce the reverse wavelength dispersion with a low non-liquid crystal material content are demanded.

Meanwhile, according to the embodiment of the invention, the composition for optical elements may include 100 to 300 parts by weight, 100 to 250 parts by weight, or 120 to 250 parts by weight of the reactive mesogenic compound per 100 parts by weight of the negative optical dispersion compound. Namely, it is preferable that the composition includes 300 parts by weight or less of the reactive mesogenic compound per 100 parts by weight of the negative optical dispersion compound in order to sufficiently induce the reverse wavelength dispersity required for the present invention. However, when the content of the reactive mesogenic compound is too low, the liquid crystal characteristics may fall. Therefore, it is advantageous for the composition to include 100 parts by weight or more of the reactive mesogenic compound per 100 parts by weight of the negative optical dispersion compound.

According to the embodiment of the invention, the composition for optical elements may further include a polymerization initiator and a solvent in addition to the reverse wavelength compound of Chemical Formula 1 and the reactive mesogenic compound.

Here, polymerization initiators and solvents conventional in the art to which the present invention pertains may be applied to the present invention without particular limitation. The content of the polymerization initiator may be determined in a conventional range which can sufficiently induce the polymerization reaction and prevent the decrease of the composition property due to excessive addition, and preferably, it may be 0.01 to 5 parts by weight per 100 parts by weight of the negative optical dispersion compound. The content of the solvent may be determined in a conventional range which can provide a proper viscosity to the composition and can induce a proper polymerization reaction. For a non-restrictive example, the solvent may be included in the composition so that the solid content (the negative optical dispersion compound, the reactive mesogenic compound, the polymerization initiator, and so on) included in the composition becomes 15 to 40 wt %, 15 to 35 wt %, or 20 to 30 wt %.

For non-restrictive examples, the solvent may be benzene, toluene, xylene, mesitylene, n-butylbenzene, diethylbenzene, tetralin, methoxybenzene, 1,2-dimethoxybenzene, ethylene glycol dimethylether, diethylene glycol dimethylether, acetone, methylethylketone, methylisobutylketone, cyclopentanone, cyclohexanone, ethyl acetate, methyl lactate, ethyl lactate, ethylene glycol monomethyletheracetate, propylene glycol monomethyletheracetate, propylene glycol monoethyletheracetate, γ-butyrolactone, 2-pyrrolidone, N-methyl-2-pyrrolidone, dimethylformamide, chloroform, dichloromethane, carbon tetrachloride, dichloroethane, trichloroethylene, tetrachloroethylene, chlorobenzene, t-butyl alcohol, diacetone alcohol, glycerin, monoacetin, ethylene glycol, triethylene glycol, hexylene glycol, ethylene glycol monomethylether, ethyl cellosolve, butyl cellosolve, or a mixture thereof. Among the solvents, a solvent of which the boiling point is 60 to 250° C. is favorable for forming a layer of uniform thickness and minimizing the residue of the solvent or the fall in orientation when the composition is coated.

The composition for optical elements may further include non-mesogenic compounds having at least two polymerizable functional groups, selectively with necessity. Said non-mesogenic compounds may be included therein for the purpose of increasing the cross-linking of the polymer, and preferably, may be one or more kinds of compounds selected from the group consisting of a C₁-C₂₀ alkyl acrylate and a C₁-C₂₀ alkyl dimethacrylate, and more preferably, it may be trimethylpropane trimethacrylate, pentaerythritol tetraacrylate, and so on.

The composition for optical elements of one embodiment may further include atomized materials for controlling the optical anisotropy or improving the strength of the polymerized layer, selectively with necessity. Said atomized materials may be atomized inorganic materials such as hectorite, montmorillonite, kaolinite, ZnO, TiO₂, CeO₂, Al₂O₃, Fe₂O₃, ZrO₂, MgF₂, SiO₂, SrCO₃, Ba(OH)₂, Ca(OH)₂, Ga(OH)₃, Al(OH)₃, Mg(OH)₂, Zr(OH)₄, and so on; or atomized organic materials such as carbon nanotubes, fullerene, a dendrimer, polyvinyl alcohol, polymethacrylate, polyimide, and so on.

II. Optically Anisotropic Body

Furthermore, according to still another embodiment of the present invention, an optically anisotropic body formed by using the composition for optical elements is provided.

The optically anisotropic body may include cured materials or polymers in which the terminal polymerizable groups of the negative optical dispersion compound of Chemical Formula 1 and at least parts of the terminal polymerizable groups of the mesogenic compound are addition-polymerized or cross-linked. Particularly, the optically anisotropic body can show the reverse wavelength dispersity satisfying the following Equations I and II because it is formed from the composition including the negative optical dispersion compound of Chemical Formula 1.

Δn _((450 nm)) /Δn _((550 nm))<1.0  (Equation I)

Δn _((650 nm)) /Δn _((550 nm))>1.0  (Equation II)

in Equations I and II, Δn(λ) means a specific birefringent index at wavelength λ in the liquid crystal phase.

Said optically anisotropic body can be obtained by coating the composition for optical elements on a supporting substrate, aligning the liquid crystal compound in the composition and then eliminating a solvent therefrom, and exposing the same to an energy ray for the polymerization.

Here, the supporting substrate is not particularly limited but for a preferable example, a glass plate, a polyethylene terephthalate film, a polyimide film, a polyamide film, a polymethylmethacrylate film, a polystyrene film, a polyvinylchloride film, a polytetrafluoroethylene film, a cellulose-based film, a silicone film, and so on may be used. The supporting substrate on which a polyimide alignment layer or a polyvinyl alcohol alignment layer is formed may be preferably used.

Any known method can be used as the method of coating the composition on the supporting substrate, and for example, a roll coating method, a spin coating method, a bar coating method, a dip coating method, a spray coating method, and so on can be applied. The thickness of the layer formed by the composition may vary according to the use, and preferably it may be selected in the range of 0.01 to 100 μm.

Meanwhile, as the method of aligning the liquid crystal compound, for a non-restrictive example, a method of carrying out pre-alignment treatment on the supporting substrate may be used. Said alignment treatment may be carried out by forming a liquid crystal alignment layer including various polyimide alignment layers or polyvinyl alcohol-based alignment layers on the supporting substrate, and carrying out a treatment such as rubbing. Furthermore, a method of applying a magnetic field or an electric field to the composition on the supporting substrate may be used.

The method of polymerizing the composition for optical elements may be a known method using light, heat, or electromagnetic waves.

The optically anisotropic body may be used for retardation films, polarization devices, antireflection layers, selective radiation layers, view angle compensation layers, and so on of a liquid crystal display or an OLED type of display. Particularly, when the optically anisotropic body formed by using the composition is applied to an OLED type of display, the interference by external light can be minimized and it is possible to realize more perfect black.

Advantageous Effects

The composition for optical elements according to the present invention makes it possible to provide an optically anisotropic body which can show a stronger and more stable reverse wavelength dispersion property. The optically anisotropic body formed by using the composition can be applied to the display devices of an LCD or OLED type as a thin-layer broadband wave plate.
